Leaky-wave Analysis and Design of a Corrugated Sectoral Waveguide

Résumé

A dispersive analysis of a fully metal corrugated sectoral waveguide is presented. This structure supports cylindrical mode and closed-form solutions are not available in literature due to the presence of the corrugations. The phase constant of the cylindrical mode is extracted by means of a full-wave calculation of the fields excited with a rectangular-waveguide feed. The sectoral waveguide is periodic modulated introducing concentric circular slots. Thus a periodic leaky-wave antenna is obtained. The radiated patterns validate the phase constant computed in the waveguide without slots
